4) Step 8 - Action message 04 SET A/T SW ARM instructs the operator to position the autothrottle switch to A/T ARM. The CPU verifies that the switch position is A/T ARM when it senses that AIM label 356, word 6, bit 10 is set to logic one. When the switch position is verified, the CPU advances to the next test step.
5) Step 9 - Action message 04 SET A/T SW OFF instructs the operator to position the autothrottle switch to off. When the CPU verifies that AIM label 356, word 6, bit 10 has been set to logic zero, the CPU advances the test routine to the next step.
6) Step 10 - Action message 04 HOLD DN HDG SEL SW instructs the operator to press the heading select switch. The CPU verifies that AIM label 356, word 6, bit 24 is set to logic one. The CPU advances to the next test step.
7) Step 11 - Action message 04 SET F/O F/D SW ON instructs the operator to position the first officer's flight director switch to ON. The CPU verifies that the AIM label 356, word 6, bit 13 is set to logic one. The CPU advances to the next test step.
8) Step 12 - Action message 04 SET F/O F/D SW OFF instructs the operator to turn off the first officer's flight director switch. The CPU verifies that the AIM label 356, word 6, bit 13 is set to logic zero. The CPU advances to the next test step.
(19) GUN 051; Ground Test - LRU - 04 MCP (Steps 7-13) (Fig. 18)
(a) MCP Test Steps 7-13 Description
1) Test steps (7-18) are verified by the CPU automatically advancing to the next test step. The test does not advance if the CPU does not verify that the switch tested is in the correct position. To continue the test past a fault, the operator presses the YES/ADV switch. There is no fault message for unlighted switch tests.
2) Step 7 - Action message 04 SET CAPT F/D SW ON instructs the operator to position the captain's flight director switch to ON. The CPU monitors AIM label 356, word 6, bit 9 to be set to logic one. Bit 9 set to one indicates to the CPU that the captain's F/D switch is in the ON position. The CPU then advances to the next test step.
3) Step 8 - Action message 04 SET CAPT F/D SW OFF instructs the operator to switch off the captain's flight director switch. The CPU monitors AIM label 356, word 6, bit 9 to be set to zero. Bit 9 set to zero indicates to the CPU that the captain's flight director is turned off. The CPU advances to the next step.

(a) MCP Test Steps 14-18 Description
1) Step 14 - Action message 04 SET BANK LIM TO 30 instructs operator to position the bank limit selector switch to 30. The CPU verifies that the AIM label 356, word 6, bits 26 and 27 are set to logic one. The CPU advances to the next step.
